Self-priming, dry-running pump systems without valves or seals eliminate fluid contamination. But inserting tubing through the chamber while maintaining proper tracking and correct tension can be challenging.

Load tubing easily and reduce maintenance time with a patented over-center cam and adjustable tubing retention that holds tubing securely in place.
